In Presbyopia, the nearest point that can be focused gradually recedes, leading to inability to read or undertake close work with the eye. Gradually patients also lose the ability to focus sharply in the middle distance.
Presbyopic lasik is a procedure that allows the patient to focus on near objects while being able to focus on distant objects.
Presbyopic Lasik modifies the curvature of the cornea creating a bilateral multifocal cornea in the treated optical zone.
Your ophthalmologist will conduct a detailed examination to determine your eligibility for Presbyopic lasik. The procedure is undertaken only when your eye doctor determines your eligibility. Patients who have undergone earlier eye surgery or those who have healing difficulties may not be recommended Presbyopic surgery.
Presbyopic Lasik has inherent advantages over Monofocal Lasik where one eye is corrected for near vision and the other is corrected for distant vision. It eliminates need for corrective lenses and offers near natural eye sight.
Refractive Lensectomy - PRELEX – Presbyopic Lens Exchange
( Multi Focal Intra Ocular Lens)
This is an IOL (Intra-Ocular Lens) replacement procedure that replaces the natural lens with a multi-focal intra-ocular lens implant.
Traditional lens replacement were fixed-focus lenses. These would offer clear distance vision but required the use of reading glasses in most cases.
Prelex offers the advantage of having a multifocal lense that reduces or eliminates the need for reading glasses.
IOL implants are suitable for patients suffering from presbyopia.
Multi-focal lens sharply reduces or eliminates the need for reading glasses.
Conductive Keratoplasty -
CK is the first alternative to laser for treating farsightedness. The procedure is also currently being tested in clinical trials for the treatment of presbyopia, the age-related progressive form of farsightedness. While hyperopia
and presbyopia both result in difficulty seeing near objects clearly, they have different causes and require different approaches for treatment.
For most farsighted patients, the CK procedure makes it possible to eliminate the need to wear reading glasses. The FDA has approved CK for the treatment of hyperopia
between +0.75 and +3.25 diopters.
CK is performed using a small probe, thinner than a strand of hair, that releases radiofrequency energy. The probe is applied in a circular pattern on the outer cornea (front window of the eye) to shrink small areas of corneal tissue. This circular pattern creates a constrictive band (like the tightening of a belt), increasing the overall curvature of the cornea to treat farsightedness. The procedure, which takes about three minutes, is done in the doctor's office with only topical anesthesia (eye drops).
